HARMAN FL8385 CD CHANGER TRAY ALIGNMENT

We've all done it, or one of our youngsters do it for us... knock the multi disc tray out of sync with the drive gears.

With multi disc trays, the CD drive has to move out of the way during disc change and tray loading. Occasionally a disc jams, someone forces the tray movement, and you hear the GRIND, GRIND, GRIND of slipping gears.

Most designs have a switch-hit gear setup that's self correcting for small adjustments but occasionally the mechanism slips beyond self correcting.

Here's the process to open up and fix the tray alignment for Harman's FL8385 CD Changer.

The problem is in the loading bay, sometimes 2 CD's will get jammed locking up the system, or the timing gear is out of sync, or possible broken gears.

SGI O2 CD-ROM drive tray repeatedly opens


I am having the same problem. I haven't resolved it entirely, but at least I managed to get it working again by the following steps.

First, disassemble the part of the computer chassis around the CD-ROM drive. Follow the instructions for "replacing the CD-ROM drive" in the SGI 02 hardware maintenance manual. It can be done in 10 minutes with a screwdriver.

After you have gained access to the CD-ROM drive itself, take off the top metal cover. Then you will be able to see the tray and the white gears underneath.

In my case, the problem seems to be caused by some misalignment between some wire springs and the white gears. Note when the CD tray closes, the manual eject button (a black plastic rod on the right) should stick out, and the white piece of plastic with a triangular end on the left should push against the front of the CD tray.

Somehow, the gears failed to push the white plastic piece all the way to the edge of the tray, and the CD-ROM drive thinks the tray wasn't fully-closed, and ejects the disc.

To force the drive to read the disc, pull the white plastic piece on the left with the triangular end towards the edge of the tray. (Pull it towards you if you are facing the front of the drive.) You might need to use some force, but I can get the drive to work this way, even though it still "sticks open" half the time.

Good luck, and if you happen to find a better solution, I look forward to hearing it.
